LINOTYPE-MACHINE.

Specification oi' Letters Patent.

Patented June 22, 1909.

Application tiled November 3, 1908. Serial No. 460,827.

To all whom fit lmay concern:

Be it known that I, JOHN R. Roonns, ot the borough of Brooklyn, countyot' hincs, city and State of New York, have invented a new and usefulImprovement in l'iinotyrnL Machines, of which the following is aspecilication.

My invention relates to power driven mechanism controlled by finger-keyst'or actuating't'he. matrix-releasing cscnlwincnts quiring to beactuated by {niger-keys. .in the lform shown, it intended moreparticularly for application to Mergenthale r line-cas ting machines ofthe character shown in Letters Patent of the United Stat-cs #436,531

In the drawings I have shown two series or rows of cscaperncnt-actuatingreeds and a correspondingr number ot actuating' devices arranged in tworows on opposite sides ot' a central line. It is to be understood,however, that when a single row of reeds` is to be actuated, the secondseries of actuating dcvices may be omitted.

Figure 1 is a vertical'transverse section through my mechanism. Fien 2 acrosssection on the line 2-2 of ltig. 1. Fig'. 3 is a View of one ot'the rubber friction rings.

Referring to the drawings, i represents one of a row or series of upright reciprocatimr reeds, each urged downward by a spring B connectedthereto. The lower end of each reed carries on a pivot C an upright camor eccentric D perforated or lightcncd on one side so that when free, itwili hang normally in the position shown on the right hand in Fig. 1. f

E represents a horizontal continuously rotating roll of metal or othersuitable material, located some distance vbelow the eccentric D. Itssurface and that of the eccentric may be corrugated or toothed ifdesired.

F represents a vertical movable wheel or idler intended to communicatemotion trom the roll to the eccentric. it is preferably provided with arubber tire or rirnf, and is pivotcd in the upper end ot a lover G,which is mounted at the lower end on a horizontal fixed pivot g, so thatby swinging the lever forward, the wheel F may be carried between andinto Contact with the eccentric i) and roll E. When this donc, theirictional engagement of the roll E will canse a rotation of the wheelF, which wili in turn impart a rotation to thc eccentric i).

As the eccentric turns, it will lii't its pivot (l, which in turn willlitt thc reed A. 'the lcvcr and roll are thrown l'orward into action bya Vfinger-key il, pivotcd at fr. i

ln order to maintain thc rol lt in action il the lingers-key is releasedbelorc the action is compict cd, [provide a latch i, pivotcd to thctrame at i, :uid provided with a shoulder i. to engage and hold thcupper cnd ol' Ithe lcvcr when thc latter is thrown forward, as indicatedin dotted lines` A spring; J connects thc lever and the latch, andserves the twol'old purposi` oll throwingr thc latch into cngngcmcnt anddrawincr thc lover and roll backward when the latch is disengaged. Thedisengagement otA the latch is automatically cll'ccted at the propertime by a pin K on the side' otr the eccentric i). then thc eccentrichas rotated a sullicicnt distance, this pin lifts thc latch and thespring J instantly rctracts the lcvcr and wheel lt so that the lit'tingrclicct terminated and the reed A permitted to lall.

E is a second roll connected with the sccond series of recds through thelover ti, roll F and (.cccntric l), the various parts being,r duplicatesot those above described, except that they are reversed or turned to thclcl't and controlled by a tingcr-kcy ll.

rIhc essence ol' the invention lios in the employment ol a movablelidler for im )arting motion from the continuously revolvin;r roll to aneccentric which lifts thc reed, and it will be obvious to a personskilled in the art that the parts may bc modified in lorm and inarrangement witlnnit essentially changing the mode of action or passingbeyond the scope oli the claims herein.

Having` described my inventionJ i claim and desire to secure by Lettersiatcnt,
